One shade whiter teeth
One shade of whitening means subtle lightening of natural tooth colour, with the result depending on stain type, enamel, dentine, and method.
The short answer
One shade of whitening means subtle lightening of natural tooth colour, with the result depending on stain type, enamel, dentine, and method. Peroxide breaks down coloured organic molecules within enamel and dentine. Crowns, veneers, fillings, and bonded areas retain their material shade and may become more noticeable.
How does peroxide change the colour inside a tooth?

What should you do before and during one-shade whitening?
Have teeth and gums checked before whitening, reduce staining drinks and tobacco exposure during treatment, and follow contact-time instructions. A dentist can compare the starting shade and plan around restorations.
When should sensitivity or uneven colour be assessed?
Seek advice for sharp or lingering sensitivity, gum irritation, pain from one tooth, or a patchy colour change. Discolouration after trauma merits examination.
